What is a three-way catalytic converter? A three-way catalytic converter is the most important external purification device installed in a car's exhaust system, which can remove CO from the car's exhaust Harmful gases such as HC and NOx are converted into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Simply put, they purify the exhaust gas. The working principle of a three-way catalytic converter is as follows: 1. When the engine exhaust gas is discharged through the exhaust pipe, due to the catalytic effect of the purifying agent in the three-way catalytic converter, the activity of C0, HC, and NOx is enhanced, leading to oxidation and reduction reactions. 2. C0 is oxidized to colorless and non-toxic C02 at high temperatures, HC compounds are oxidized to H20 and C02 at high temperatures, while NOx is reduced to N2 (nitrogen) and 02 (oxygen), thereby purifying the engine's exhaust emissions)

Method for installing a three-way catalytic converter

Method for installing a three-way catalytic converter: ① Use 8 bolts to install 2 heat shields on the new preheated three-way catalytic converter. ② Install the new gasket, protective ring, and sealing gasket onto the preheated three-way catalytic converter. ③ Use 3 bolts and 2 new nuts to install the preheated three-way catalytic converter with a tightening torque of 29N. m. ④ Use bolts and nuts to install the exhaust manifold bracket with a tightening torque of 42N. m. ⑤ Use bolts and nuts to install the No.1 exhaust manifold bracket with a tightening torque of 42N. m. ⑥ Connect the secondary oxygen sensor connector

SUBARU BRZ introduce

The Subaru BRZ was officially released in 2015, with a more sporty exterior design and equipped with 225/40 ZR18 Michelin Pilot Super Sport series tires. The chassis has been strengthened, and the power continues to be equipped with a 2.0L naturally aspirated direct injection engine. The Subaru BRZ tS STI model is currently only sold in Japan, with a limited quantity of 300 units [1] Subaru unveiled the 22 seater new two door hardtop sports car BRZ at the Frankfurt International Auto Show, which opened on September 15, 2011. The new car showcases Subaru's latest research and development achievements, as well as the new generation design concept, pointing the way for future Subaru new cars. The new BRZ is a collaborative development between Subaru and Toyota, and is a sister car of the Toyota 86 (note: the North American version is called the Scion FR-S, the European version is called the GT86, and the Japanese version is called the 86), The car adopts a horizontally opposed engine and front rear wheel drive layout. The suspension forms are front MacPherson independent suspension and rear double wishbone suspension. The wheelbase reaches 2570mm, the car is 4239mm long, 1775mm wide, and 1285mm high
